Novel material taking cyanogen-containing silicone oil as continuous phase and used for magnetic fluid tire sealing

Abstract

The invention discloses a novel material taking cyanogen-containing silicone oil as a continuous phase and used for magnetic fluid tire sealing and belongs to the technical field of tires. The formula of the novel material is characterized by comprising the cyanogen-containing silicone oil, barium sulfate powder, nano-scale samarium cobalt magnet powder, nano-scale ferrite magnet powder, diethyl ethylene diamine, magnesium stearate, rosin amine, isoprene rubber granules and an acrylate adhesive. The novel material is mainly applied to a radial tire adopting a steel wire tire cord layer, doesn't affect the dynamic balance of wheels, can rapidly and automatically repair a notch with the diameter smaller than or equal to 10 mm, is not dried up, doesn't freeze and is high in reliability and stability and durable. After use, with rotation of the wheels, a circle of magnetic fluid is uniformly applied to the inner wall of the tire. The magnetic fluid can be stably and uniformly applied to the inner wall of the tire through the suction action of the steel wire tire cord in the tire, the dynamic balance of the wheels is not affected, and revolutionary improvement is really realized by comparison with the prior art.

Description

technical field [0001] The invention belongs to the technical field of tires, and relates to a new self-replenishing material applied to radial tire sealing, in particular to a new magnetic fluid tire sealing material containing cyanosilicone oil as a continuous phase. Background technique [0002] Automobiles and various motor vehicles have become one of the important symbols of modern civilization. During their use, tires are punctured by nails or sharp hard substances on the road surface to cause deflation, which often causes the vehicle to fail to operate normally. The earliest automatic tire sealant was applied in the US military wheeled vehicles in the 1920s and 1930s. The tires of military vehicles were filled with automatic tire sealant. It has a history of 80-90 years. The advantage of the automatic tire repair fluid in the prior art is that it can be repaired in 3 seconds without removing the tire; however, it also has many disadvantages: 1. It affects the dynamic ...

AI Technical Summary

Problems solved by technology

The advantage of the automatic tire repair fluid in the prior art is that it can be repaired in 3 seconds without removing the tire; however, it also has many disadvantages: 1. It affects the dynamic balance of the wheel: when a can of automatic tire repair is used After the liquid is removed, 200ml-300ml of liquid remains on the inner bottom of the tire. This liquid makes the wheel run like an eccentric wheel, which not only increases the noise, but also reduces the stability, thus affecting the dynamic balance and belt when the wheel is running. There is a certain degree of traffic safety hazard

2. When the diameter of the tire wound is greater than 6mm, the automatic tire sealant does not work

3. There are also some inflatable tank type automatic tire sealant products, the ingredients of which can only temporarily inflate the flat tire and reduce leakage, until the vehicle is driven to the nearest repair station

4. Some tire sealant products will dry up inside the tire or freeze in cold weather, not only lose the sealing effect, but will damage the inner wall of the tire
